Shortwave Radiogram, programs 26 and 26-S, 16-17 December 2017:

Friday, December 15 2017

Hellofriends,

Sorry about there run during last weekendâs broadcast Saturday at 1600-1630 UTC broadcast on 9400kHz. Listeners who did not receive the promised Flamp transmission can decode from audioprovided by Roger in Germany and video provided by Scott in Ontario. Another Flamp item will be broadcast this weekend.

Most of this weekendâs Shortwave Radiogram will be in our usual MFSK32, with four images.But we will also include three 8PSK modes: 8PSK-125FL, 8PSK-250FL,and 8PSK-500F.The RSIDs should switch Fldigi to the correct modes. If you must change modes manually, note that the first two are 8PSK-125FL (not -125F)and 8PSK-250FL (not -250F). You can read about the 8PSK modes here. (Sorry, these 8PSK modes are not yet available on TIVAR or AndFlmsg.)

This time we will use smaller blocks with Flamp, to improve the chances that the file is received 100%. There will be 25 blocks of 240 bytes each, transmitted fourtimes. If the file is received 100%, click Flampâs File > Folders > rx,and the file China_internet_conference.txt should be found in the folder forthe date of reception.

If possible,record your reception. You can try to decode the 8PSK items,including the one in Flamp, several times. Experiment with different audio players (Windows versus VLC, etc) and different equalizer settings, compressors,and other audiotricks.

The Slow Show. This weekend, the broadcast Sundayat 2330-2400 UTC, providing poor reception in most parts of the world as we approach the winter solstice,will entirely be in the Olivia 128-2000 mode. This is avery slow mode, only 17 wpm, but it might be able to overcome difficult conditions. Even if you cannot hear the tones or see a trace on your waterfall,you might still be able to decode the text. Make sure that Fldigiâs squelch(SQL) is off. If your reception is bad, this could be interesting. If it is good, this will be as muchfun as watching paint dry. There is noRSID for Olivia 128-2000, so you need to set it manually. Under the Fldigi OpMod menu, select Olivia > Custom: then dial up a bandwidth of 2000 Hz, with128 Tones. Again, record your reception if possible. You can then experiment with the integration period in that same menu. If you increase the number of FEC blocks, your decode might improve. It will also increase the delay time between hearing the tones and seeing the text print out, but this is less ofa problem in receiving a broadcast than in an amateur radio QSO. Readabout Olivia, including the integration period, here. Also try different audio players and settings. (Sorry again: TIVAR and AndFlmsg donot include Olivia 128-2000.)
